A resin used in emulsion paints.

The dredging industry needs cutters for many kinds of dredging work. The basic cutter skeleton consists of a hub, a ring and several curved arms linking them.

A strong steel structure installed between hatches to permit the stowage of an additional tier of containers or heavier containers in the upper tier. Lashings can be applied at a higher level but can also remain short.

According to The Motor Ship November 2005 The technically advanced self-propeller and ocean-going mega cutter suction dredger d’ARTAGNAN was delivered in October 2005 to the French dredging contractor SDI.

Wires, chains, ropes, or straps used to secure cargo on a ship. See also container lashing equipment.

Weight per a unit of length of a ship as a function of her length.

A curve indicating the area of water plane corresponding to any draft.

A barge carrier designed to act as a shuttle between ports, taking and discharging barges (lighters). The ship is provided with massive crane which loads and discharges the lighters over the stern.

The projection on the plane of inclination of the locus of the centre of buoyancy for varying inclinations with constant displacement.

A joint between two overlapping members in parallel plane.

Prominent objects on land (churches, towers, high buildings, etc.), beacons and lighthouses serving as guides to steer by, when approaching an estuary, river or harbour.

An excessively large, laminar, non-metallic inclusion, producing a defect appearing in sheets or strips as segregation or in layers. Severe lamination can be repaired by a local insert plate.

A curve showing the height of the transverse metacenter above base line corresponding to any displacement.

A type of ship which trades only in the Great Lakes of North America. They usually carry grain and ore cargoes.

According to SOLAS, the Master of the ship shall be supplied with reliable information to enable him assessment of the ship stability.

A curve whose ordinates are areas of cross sections up to a given waterline corresponding to each point in the length.

Ships not in active service; a ship which is out of commission for fitting out, awaiting better markets, needing work for classification, etc.

The plot of the righting arm GZ calculated as function of the heel angle at constant displacement and vertical centre of gravity KG.

An insulating material applied to surfaces of pipes, or the boiler casing in order to reduce heat transfer.

Steps used aboard ship in place of stairs. The angle of inclination for a vertical ladder should be between 75–90 degrees. Continuous ladders should not exceed 9.1m (30 ft) in height.
